Not sure what size kitchen chimney you need for your kitchen? Don’t worry, we have got you covered!
In this guide, we’ll share a smart kitchen chimney size calculator that will put guesswork away and make your kitchen chimney size decision much easier.
How To Calculate The Size Of My Kitchen Chimney?
First things first, to calculate the ideal kitchen chimney size, you need to know these two things:
- Suction Power (750 m3/hr – 1500 m3/hr)
- Kitchen Chimney Size (60 cm or 90 cm)
Here’s the Kitchen Chimney Size Calculator In Feet. It calculates both suction power and size. Fill in the input fields and hit calculate to get the result. But we highly recommend reading on till the end for more information related to this topic and clear all doubts.

Kitchen Chimney Size Calculator For Suction Power - How To Calculate
The first step is to calculate your kitchen chimney's required suction power. The suction power is the capacity of the kitchen chimney to extract air from the kitchen per hour. It is measured in cubic meters per hour - "m3/hr."
In the Indian market, you'll find kitchen chimneys with various suction power. But mostly, they start from 750 m3/hr to 1500 m3/hr.
How does this kitchen chimney calculator work?
Okay, so it is based on the simple principle of the volume of your kitchen times 10. Why? Because as a general rule, a kitchen chimney should be capable enough to extract the air from your kitchen at least 10 times an hour.
So, how to use this kitchen chimney-size calculator?
Well, just put the sq. ft. value of your kitchen and the height of your kitchen in ft.
It's very easy to get.
Just input the kitchen sq. ft. and the height, and press the calculate button, the calculator does the heavy lifting for you. It instantly gives the required suction power for your kitchen chimney.
EXAMPLE CALCULATION:
Kitchen Size: 80 sq. ft. (8 By 10 kitchen)
Kitchen Height: 10 ft
So, after calculation using the above tool, you get 226.53 cubic meters per hour. That means, at least you'll need to have a kitchen chimney of 226.53 m3/hr for your kitchen.
Now generally, the size of the example kitchen is a standard size of an Indian kitchen. And most kitchen chimneys are available with a suction power of more than 750 m3/hr.
So in a nutshell, you don't have to worry about the suction power of a kitchen chimney. As long as it is at least 750 m3/hr to 800 m3/hr, you're good to go with it.
However, if you're purchasing it for a big-sized kitchen where the suction power of the chimney will play a crucial role, then definitely, consider the suction power carefully.
Our calculator should help you form the right estimations of your ideal kitchen chimney size. But wait there's more. You also need to consider the width of your kitchen chimney along with the suction power.
Key Factors Influencing Kitchen Chimney Suction Power
Ducting
Ducts are the pipes that carry the smoke outside. If they are too long or have multiple bends the suction decreases. Shorter and straighter ducts work best.
Filters
Filters are like sieves that trap grease and other particles. Over time, these can get clogged. Imagine a blocked drain; water won't flow well. Similarly, if filters are dirty, suction power drops.
Motor Strength
The main power source of your chimney's suction is its motor. So, a powerful motor means stronger suction.
Size and Design
Size matters here. A wider chimney covers more area on your cooktop, sucking up more smoke and fumes. Also, the design plays a part. Some chimneys have better internal designs that enhance suction efficiency.
Type and Amount of Cooking
What you cook and how much you cook also matter. Heavy, smoky cooking needs more suction power compared to light cooking.
Here’s How To Maximize Your Kitchen Chimney Suction Power
Choose Chimney Of Optimal Size and Motor Power
The chimney size should ideally extend about 3 to 6 inches beyond your stove's dimensions on each side. For motor power, aim for at least 500-1000 cubic meters per hour (m³/hr) for typical home cooking depending on the size of your kitchen and duct length.
Ducting Dynamics
The ideal duct length should be no more than 12 feet with minimal bends. Use smooth, wide ducts (preferably with a diameter of 6 inches) for better airflow.
Filter Upgrade for Heavy Usage
If your cooking involves a lot of smoke or deep frying, upgrade to professional-grade baffle filters. These can handle higher volumes of smoke and grease more effectively.
Unobstructed External Vents
Regularly check the external vent for obstructions like bird nests or debris. Even a 10% blockage can reduce efficiency significantly.
Kitchen Chimney Width - Here's How To Calculate
Now the width of the kitchen chimney also plays a key role in determining whether or not it can effectively remove smoke and dust air from the kitchen.
The general rule is to get a kitchen chimney of width similar or more to the length of your gas stove.
Normally, most kitchen chimneys you will see are either 60 cm or 90 cm.
So how to decide which kitchen chimney size will be best for your kitchen?
Well, here's a chart to give you an idea:
| No. of Gas Stoves | Kitchen Chimney Width |
| 2 | 60 cm [0.6 m / 23.62 in / 1.97 ft] |
| 3 and above | 90 cm [0.9 m / 35.43 in / 2.95 ft] |
If you have a 2-burner gas stove, then the suitable kitchen chimney size would of 60 cm. Here's one of the best 60 cm Kitchen Chimney:
However, if you have a 3-burner gas stove or more no of burners, then the suitable kitchen chimney size would be 90 cm. Here's one of the best 90 cm Kitchen Chimney:
How exactly measure the required width of the Kitchen Chimney? Well, first take a measuring tape and then get the length of your kitchen stove.
Then convert it into cm. The answer you get is the required width of the kitchen chimney.
Our Kitchen Chimney calculator we shared earlier should help you with that.
EXAMPLE KITCHEN CHIMNEY CALCULATION:
Let's say you measured your gas stove and the length (horizontal span) of the gas stove is 30 inches.
1 inch = 2.54 cm
So with 30 inches, you will require 30*2.54= 76.2 cm
So this means you will need a 90 cm kitchen chimney so that it has enough span to cover the whole kitchen stove.
Final Thoughts
So there you have it - a kitchen chimney calculator - which calculates both size and suction power.
Normally, a suction power of at least 750 m3/hr is sufficient. But for bigger kitchens and depending on the type of cooking, you can go with a chimney of at least 1000 m3/hr or more.
The size of the chimney largely depends on the size of your gas stove. The bigger span is helpful if you have a longer-width gas stove and vice versa. Now here are some of the common questions related to Kitchen Chimney Size that you could be having as well. Go through them and clear all your doubts.
FAQs
What is the meaning of 60 cm or 90 cm in a chimney?
In a kitchen chimney, the span of the chimney over the kitchen counter is measured as 60 cm or 90 cm. The smaller-sized chimney is suitable for compact places where the gas stove underneath has only 2 burners. However, a 90 cm kitchen chimney is required for gas stoves with 3 or more burners.
Is a 60 cm chimney enough for 4 burners?
A 60 cm chimney is not enough for 4 burners because most 4 burner stoves have a length of more than 60 cm. However, if it is 60 cm or less then it should do well. The idea is to ensure the chimney has enough span to cover the stove and extract all the smoke and gases produced from the stove.
Which chimney is better 60 cm or 90 cm?
Both 60 cm and 90 cm kitchen chimneys are better and their specific use cases depend on the size of the gas stove and the space available in the kitchen. If you think you'd purchase a bigger gas stove that could outrun the span of a 60 cm chimney, then it is better to buy a 90 cm chimney. Other than that, the quality of the product depends on the brand and the material used while manufacturing it.
How much space should I leave on the sides of the kitchen chimney while installing?
Well, a 2-3 inches gap on either side of the kitchen chimney should be enough. The idea is to have enough space for the chimney to be removed or installed easily whenever you need it. So having a little bit of gap on either side is helpful.
How much height should be there between the kitchen chimney and the countertop?
As a general rule, have around 25 inches between the gas stove and the kitchen chimney. This size is perfect to ensure the kitchen chimney can effectively work and extract all the smoke and gases from cooking.
